Production

Work out what each production run really costs: materials, labour, machines and expenses, then share the month’s bills over what was made.

What is production costing?

When you make a product from other items — a kit from parts, a bottled liquid from raw materials, a meal from ingredients — production costing tells you what each run really cost. It is part of Inventory Tracking, and it adds four things to Item Assembling:

  1. Job orders — produce against a customer's sales order and see how much of each item is made.
  2. The full direct cost on every production entry — the materials actually used (compared with the bill of materials), the hours of your staff and outside labour, the hours of each machine, and expenses such as electricity.
  3. Month-end expense distribution — bills that come for the whole factory (rent, power, branding…) are shared over the month's production, either into the stock cost or only into reports.
  4. Production reports — cost sheet, wastage, yield, labour, machine use, expense shares, unit cost trend and job order status.

Key terms

TermMeaningExample
Production entryOne production run, entered in Item Assembling: the finished item and quantity made, and everything used to make it100 × KIT-1 on 14 Oct
Bill of materials (BOM)The item's recipe: the components and quantities for one unit. It fills the materials of a production entryKIT-1 = 2 × PART-A + 1 × PART-B
Job orderA production order made from a customer's sales order. Its items are the sales order's items; its status is worked out from what was producedJob for SO-123: KIT-1 ordered 100
Absorbed costLabour and machine cost moved into the value of the stock produced. When the entry is posted, the finished item's stock is debited and a labour absorbed / machine absorbed account is credited; the wages and depreciation themselves are booked as usual by payroll and fixed assets7.5 h × 23.08 = 173.08 labour absorbed
Book costWhat goes into the stock value: materials + labour + machines + expenses on the entry1,693.33 for 100 kits = 16.9333 each
Full costBook cost plus the shares of month-end expenses distributed to the entry, including the shares kept out of stock (report only). Used for pricing and management1,693.33 + 250 rent + 200 branding = 2,143.33
Expense typeA kind of period expense with the accounts it is booked to, a default basis and a default treatmentRENT: factory rent account
DistributionA document that shares one expense type's bill for a period over that period's posted production entriesOctober rent 1,000 over 2 entries
TreatmentAdd to stock cost (the share raises the item's cost; the part already sold goes to cost of sales) or Report only (nothing is posted; the share shows in full cost only)Rent → Add to stock cost; branding → Report only
BasisHow a bill is shared between entries: output quantity, machine hours, labour hours, material value, production cost, or a typed shareBy output: 100 kits get 25 % of 400

A job order is optional: a production entry can also be made without one.

Why two costs: book cost and full cost

Accounting rules for stock (IAS 2, used in Saudi Arabia and most countries) allow only production costs in the value of stock: materials, direct labour, and factory overheads such as factory rent, machine depreciation and factory power. Administration and selling costs — head office, branding, marketing — may not be put into stock value; they are expenses of the period.

Management still wants to see them per unit for pricing. So each production entry has:

  • Book cost — the stock value. It is posted, and it sets the item's average cost.
  • Full cost — book cost plus every share distributed later, including the report-only shares (branding, admin). It appears on the cost summary and the reports, never in the accounts.
Example: 100 kits have a book cost of 1,693.33 (16.93 each). At month end, 250 of factory rent is distributed to them with Add to stock cost (the kits still in stock get dearer; the share of the kits already sold goes to cost of sales), and 200 of branding with Report only. Full cost: 1,693.33 + 250 + 200 = 2,143.33, or 21.43 per kit — the figure to price with.

Batches

Production entries work with Inventory Tracking batches: the finished item can go into a batch with its expiry date, and components can be taken from chosen batches. See Batch Allocation → Batches in Item Assembling.
